This study is the only paper that we are aware of to examine Cav1 expression as a cancer disparity and is highly relevant due to the studies showing that an inverse correlation exists between epithelial and stromal Cav1 expression in cancer tissues (24), therefore one may extrapolate from this that stromal expression of Cav1 would be lower in black men with prostate cancer. The gene discussed is CAV1; the disease is cancer.
